How does water quality affect food?

Water quality can be affected by poor planning of industrial sites, animal farms, and barnyards and feedlots. Until recently, the type of water source has been indicative of the potential risks of contamination. Poor water quality can affect the quality of food crops and lead to illness in those who consume them. For example, the water may contain germs that cause human disease. Irrigating crops with contaminated water can then lead to contaminated food products which lead to illness when eaten. Groundwater, for example, has been considered one of the safest sources of water. However, depending on field location and field size, it may not be possible to use water from these sources for irrigation.
